My transcription from the album "I Belong to Glasgow: Greatest Hits of Will Fyffe" (2011), as found at Spotify:


UNCLE MAC
As sung by Will Fyffe

I landed from the colonies a week or two ago,
Where I made a lot o money, an I'm proud to let ye know
Upon an emigration scheme I sailed frae Scotland's shore.
Noo I've seen all I want to see, an I'm sailin back once more.

CHORUS: I'm rich Uncle Mac from the colonies way back.
I landed hame withoot the slightest warnin,
But I found relations funny; for they're after all ma money,
So I'm sailin back again tomorrow mornin.

I'd about a thousand relatives ta meet me on the pier.
Half o them were roond ma neck; the others on ma ear.
'Twas uncle this an uncle that an "How much have ye got?"
I don't know who to leave it to, so I think I'll keep the lot.

CHORUS: That's why I'm rich....

[Patter omitted.]

[Repeat chorus.]
